Failure to rotate the drum at high speeds when water is draining often indicates a malfunction control module or a critical imbalance of laundry that the system could not compensate for. If your Samsung washing machine does not spin, but hums when you try to pick up speed, most likely the graphite brushes of the motor are worn out or there is a break in the tachometer circuit. In situations where there is water in the tank and the program freezes, the first step is to check the drain filter and pipes for blockages that are blocking the operation of the pump.
Diagnostics must begin with an analysis of the behavior of the device: is the unit trying to accelerate the drum, is the sound of a running pump audible, and is any indication displayed on the display? error code. Modern models Samsung equipped with a self-diagnosis system, which, if a malfunction is detected, blocks the spin mode to prevent breakdown. Ignoring initial symptoms, such as extraneous noise or vibration, can lead to the failure of expensive components, including the bearing assembly or electronic board.
Often the problem lies not in a mechanical failure, but in a software failure or improper operation, for example, overloading the drum. Before calling a technician, you should perform a basic check: make sure the socket is working properly, the hoses are intact, and there are no foreign objects between the tank and the drum. Understanding how the main components operate will help you determine whether complex repairs involving disassembling the housing are required or whether simple filter cleaning is sufficient.
Analysis of error codes on the display
Modern washing machines Samsung display digital symbols on the screen that accurately indicate the nature of the malfunction. If the spin does not occur, most often users see codes related to drainage problems or imbalance. For example, error 5E or E1 indicates that water is not leaving the tank, which makes it physically impossible to switch to the spin cycle. The control unit blocks drum rotation at high speeds to avoid water hammer and damage to the seals.
Another common code is Ub or U6, which indicates a severe imbalance in the laundry. In this case, the electronics tries to fluff things up several times by adding water and rotating the drum in different directions. If the load cannot be equalized, the program interrupts the spin cycle, leaving the clothes wet. Sometimes the cause of a false response of the imbalance sensor is a misalignment of the washing machine itself or a malfunction of the shock absorbers.
⚠️ Attention: If the error code flashes on the display, do not try to forcefully switch the mode or turn off the machine immediately. Write down the combination, as it may disappear after a reboot, but will remain in the module’s memory for the master.
To accurately determine the cause, you must check the instructions for the specific model, since the designations may differ slightly in different series. Some errors like 9E, indicate power surges in the network, which can also lead to engine malfunctions and spin failure. In such cases, power stabilization often solves the problem without interfering with the design.
Problems with water drainage as a reason for stopping
The most common technical reason why the spin cycle does not work is the inability to pump water out of the tank. Drain pump in washing machines Samsung designed to work with relatively clean water, so small objects, lint and scale gradually clog the impeller or pipes. When the water level sensor (pressure switch) detects that liquid remains in the tank, it sends a signal to the control module to prohibit rotation of the drum.
The diagnostic process should begin by inspecting the drain filter, which is usually located on the lower right side of the housing. Before unscrewing it, you must place a flat container, as the remaining water will flow out of the hose. Often coins, buttons or hairballs are found inside, which mechanically block the operation pumps. If the filter is clean, but the water does not flow out, you should check the corrugated pipe running from the tank to the pump for internal creases or blockages.
- 🔍 Check the drain hose for kinks and lifting height (no more than 80 cm from the floor).
- 🧹 Clean the pump filter from debris and rinse it under running water.
- ⚙️ Listen to the pump: if it hums but does not spin, the impeller may be jammed.
- 🔌 Check the electrical contacts going to the drain pump for oxidation.
If mechanical cleaning does not help, the pump motor itself may have failed or the winding has burned out. Some models Samsung There is a breakdown of the plastic impeller, which rotates on the shaft, creating the illusion of the motor running, but not pumping out water. Replacing the pump in such cases is the only effective solution.
☑️Drain system diagnostics
Motor malfunctions and brush wear
The engine is the heart of the washing machine, and its inability to develop the required speed directly affects the quality of the spin cycle. In models with a commutator motor, the most common problem is critical wear of the graphite brushes. When the length of the brush becomes less than the permissible value, contact with the commutator is broken, sparking increases, and the engine stops rotating or runs jerkily.
You can tell if the brushes are worn out by a characteristic cracking or sparking sound at the rear of the machine during operation. If the Samsung washing machine hums, but the drum does not spin, this may also indicate an interturn short circuit in the winding or jammed motor bearings. Replacing brushes is a procedure that can be performed at home if you have basic tools and the skills to disassemble equipment.
It is also important to check the tachometer - a small element that controls the speed of rotation of the shaft. If it comes loose or fails, the control module does not receive correct speed data and emergency stops the process. This is a safety mechanism that prevents the drum from accelerating to uncontrolled speeds, which could lead to destruction of the tank.
⚠️ Attention: When replacing brushes, be sure to use original components or high-quality analogues. Cheap brushes may contain abrasive inclusions that will quickly damage the engine commutator.
How to check motor brushes
Remove the rear cover or remove the engine. There are two brush holders located on the commutator. Remove the brushes and measure their length. If the working part is less than 1.5 cm, replacement is required. Also inspect the manifold for the presence of black carbon deposits - this should be carefully cleaned with an eraser.]
Malfunction of the pressure switch and heating element
It would seem that the heating element (heating element) and the water level sensor are not directly related to the spin cycle, but in the algorithms Samsung everything is interconnected. If the heating element has a breakdown in the body or is faulty, the control module can block high speeds for electrical safety purposes. Likewise, contact sticking pressure switch leads to the fact that the “brains” of the machine think that the water has not yet left or, conversely, that the tank is empty, although this is not the case.
Checking the heating element is performed with a multimeter in resistance measurement mode. The normal value for a working element is from 20 to 40 ohms. Infinity will indicate an open circuit, and zero will indicate a short circuit. It is also important to check the resistance between the contacts of the heating element and the housing - there must be an infinitely large resistance there, otherwise it will penetrate the housing, which is dangerous for the user.
The pressure switch requires checking the integrity of the membrane and the tube going to the tank. If there is water or blockage in the tube, the sensor will not be able to correctly monitor the fluid level. As a result, the machine may not start spinning, believing that the water has not yet been completely drained, or, conversely, it will try to spin a full tank, which will cause strong vibration and an emergency stop.
Mechanical damage and wear of components
Long-term operation without preventive maintenance leads to natural wear of mechanical parts. Shock absorbers and springs that hold the tank lose their properties over time. If the shock absorbers are “dead,” the tank begins to hit the body walls violently when trying to accelerate, and the vibration sensor forcibly reduces the speed to a minimum or stops the car.
Bearing wear is another serious problem. If you hear a hum, grinding noise or play when you rotate the drum by hand, it means the bearings are damaged. Operating the machine in this condition is prohibited, as this can lead to destruction of the shaft and damage to the tank. In modern models Samsung with non-separable tanks, replacing bearings requires a complete replacement of the tank assembly, which is often not economically feasible.
The drive belt is also subject to inspection. A stretched belt can slip on the pulley, not transmitting the necessary torque from the engine to the drum. Visually, this manifests itself in the fact that the motor hums and rotates, but the drum stands still or barely moves. The tension should be such that the belt bends by about 1-1.5 cm when pressed with a finger.
Checking the shock absorbers: Press the tank from top to bottom through the hatch. If the tank moves easily, as if on a spring, and does not return with a jerk, or, on the contrary, is tightly clamped, the shock absorbers require replacement. Normally, it should return to its original position quickly and without swinging.]
Diagnostic table for main faults
To systematize the data obtained and quickly identify the node that requires intervention, it is convenient to use a pivot table. It helps correlate symptoms with likely causes and necessary actions.
| Symptom | Probable Cause | Error code (example) | Action |
|---|---|---|---|
| Water in tank, no rotation | Filter clogged or pump broken | 5E, E1 | Cleaning the filter, replacing the pump |
| It hums but doesn't turn | Engine brush wear | No | Replacing graphite brushes |
| Strong vibration, reset | Imbalance or shock absorbers | Ub, U6 | Distribute laundry, replace shock absorbers |
| Sparking, burning smell | Breakdown of heating element or motor | 9E, E4 | Replacing the heating element or motor |
| The belt comes off | Belt stretch or pulley play | No | Replacing the belt, checking the pulley |
The main conclusion: 80% of problems with a lack of spin in Samsung washing machines are associated with a simple blockage of the drain system or wear of the motor brushes, which can be fixed independently.]
Frequently asked questions (FAQ)
Is it possible to run the "Spin only" mode separately?
Yes, most models Samsung They have a separate spin program or the ability to select a function through the mode settings button. However, if the reason for the stop lies in a malfunction (for example, the water has not drained), the machine will again display an error and will not start spinning until the problem is fixed.
Why does the machine spin, but things remain wet?
This may be due to the low spin speed selected by the user, or because the machine is unable to reach full speed due to imbalance or wear on the motor. It is also worth checking whether the holes in the drum are clogged with scale, preventing water from escaping.
How to reset an error on a Samsung washing machine?
Usually it is enough to unplug the machine for 10-15 minutes. If the error is caused by a temporary electronic failure, it will disappear. If the malfunction is physical (the pump burned out, the heating element broke), the error will appear again immediately after trying to start the program.
Is it dangerous to change motor brushes yourself?
Replacing the brushes requires disassembling the machine and removing the motor. If you have the skills to work with the tool and understand safety precautions (be sure to unplug it!), you can really do it yourself. The main thing is to install the brushes correctly and grind them in.
What should I do if the machine hums during the spin cycle, but does not rotate?
Most likely, the motor or drum bearing is jammed, or there is a break in the winding circuit. It is necessary to stop operation so as not to burn the control module, and carry out diagnostics of the mechanical part.
